In our experience last week with the CBR buses, the bus ride lengths ranged from "way too long" to "incredibly, imhumanly long." It may have just seemed that way because we had to wait a long time at our bus stop, then wait while it stopped about three hundred more times in the resort, then drove on some back road that was five times longer than the route we took in our car.
Okay, so maybe I'm exaggerating a little, but we took the bus just a few times there and it was a painful experience. It took an hour and a half to get back from the MK one afternoon, between waiting half an hour for a bus, then waiting for all the other resort stops before our own.
